Question:

Histology--Hematopoietic, NOS: When both the path and clinical diagnoses simultaneously reflect reportable diagnoses but one is a worse form of the same disease process, which diagnosis do we code? See Description.

Discussion:

Would this case be coded to RAEB or AML? Bone marrow diagnosis: Hypercellular marrow with profound trilinieage dyspoietic changes. Comment: the features are consistent with RAEB. Clinical diagnosis five days later states: Myelodysplastic syndrome, early acute myelocytic leukemia (likely AML).

Answer:

For cases diagnosed prior to 1/1/2010:When several diagnoses are made as part of the diagnostic process within two months, code the one with the worst prognosis.

Code the case example as acute myelocytic leukemia.

For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
